Statistics and Measurement

We are at the forefront of efforts to improve disability data and statistics. Our efforts in this area include conducting and developing question modules for the new National Beneficiary Survey, documenting the federal surveys that collect information about people with disabilities, collecting survey data for the 2012 National Longitudinal Transition Study (NLTS-2012), a five-year study focused on youth ages 13 to 23, their educational experiences, and their transitions to adulthood, and developing and maintaining a longitudinal analytic research file on working-age DI and SSI beneficiaries, using the Social Security Administration's Disability Analysis File (DAF).
